It really does depend on the idea, but I think a good rule of thumb is to try to have something in the hands of users between 2-3 months. 1. Map put all the ideas for the product on paper 2. Build a basic form of a UI through wireframes (Balsamiq etc.) 3. Analyze the product roadmap and trim down the product features to something that is achievable in 2-3 months. 4. Make two graphical layouts for the UI, one which should be as simple as possible, and one which is pretty to look. The reason is good design takes time and can often hinder the project. That is why a simple graphical layout is good to have while coding so that the basic functionality is there. 5. Start programming towards the specific trimmed down feature set 6. Make it pretty 7. Rinse and repeat
